DIAL FOR WATCHES AND CLOCKS.

4 SPECIFICATION forming part of Letters Patent No. 262,513, dated August 8, 1882-.

Application filed May 9, 1881. (No model.)

the city of New York, County of New York,

and State of New York, have invented certain new and useful Improvements in Time-Pieces,

fully described and represented in the follow-` ing specification and the accompanying drawngs, i'orning a part of the same.

The object of my invention is 'te provide time-pieces with means whereby the ordinary hands thereof, witloutbeing moved independently oi' the motion imparted to theni by the ordinary time-movement,mayindicate'thetime at any two localities at once.

My invention consists in the employment, with a time-piece having an ordinary fixed dial and minute and hour hands, of two supplemental independently-adjustable dials, one having in its face minute-divisions and the other having on its face hour-divisions and fracticns of hours, said supplemcntal dals be ing arranged so that they and the ordinary hands and the 'ordinary fixed dial can be seen and inspected simultaneously, and said supplenental dials being set with reference to the ordinary hands without moving such hands independently of the movement imparted to them by the ordinary time-piece movement to indicate the time at any place where it difi'ers from that in the place where the hands with reference to the ordinary fixed dial indicate the time.

My invention further consists in details of construction, hereinalter fully described and claimed.

In the drawings I have shown one form of apparatus, which is the best I have deviscd in carrying out my invention, Figure l thereof being a plan View ofahunting-case watch, with the lid open, containing'myinvention, Fig. 2 being a vertical Iongitudinal section of a portion of the same, taken in the line ma; of Fig. 1. Fig. 3 is an enlarged partial section of the same, and Fig. 4 is a bottom View of a section of the plate 4. Figs. 5, G, 7, and 8 are views of modifications of the apparatus shown in the other figures containing my invention.

1 is the' upper of the two plates between which the watch-movement is placed& It is provided with a bezel, 2, into which a fiangc,

`utes, on its face.

3, on a metal plate, 4, is sprung, and by which' the plate JE- is held. This plate is provided *with fianges 5, 6, and 7. Between the fianges 5 and 6, and resting upon this plate,is a. sup plemental independently-adjustable annular dial,` 8, having sixty divisions, indicating min- It is provided with a circular rack, 9, rigidly connected thereto, for which agro'ove, 10, in the plate 4, is made, to permit ot' its movement. Between the flanges 6 and 7 is a second supplenental independently-adjustable annular dial, 11, divided on its face into hours and preferahly quarters of hours This dial is also provided with a cireilar rack, 12, which also projects into a groove cutin the plate 4, to permit it to move.

Journaled partly in the flange 3 and partly in the hezel 2 at one end, and in a small box, 13, at the other end, is a shaft, 14, having upon its inner end a pinion, 15, gearing With the cireular rack 9, and at its outer end with a milled wheel, 16, by means of which the dial S maybe turned in either direction by removing the finger or thunb over said wheel; also, journaled partly in the llange 3 and partly in the bezel 2 at one end, and in a box, 17, at the other end, is a shalt, 21, provided with a pinion, 18, gearing into the racl; 12, and at its outer -end provided with a milled wheel, 10, whereby the dial ll may be turned in either direction by running the finger or thunb over the milled wheel .19. Apertnres in the rini holding the` Crystal are made to permit the sha'ts 14 21 .to

pass. After the dials 8 and 11 are placed be tween the respective fiangcs 5 and G and 6 and 7 the flanges 5 and 7 are burnished over the slightlybcveled edge of each of said dials to prevent them froni moving out from between said flanges. W'itlin the flange 7 is placed the ordinary fixed dial 20, which is held in place by studs passing through the plate 4, and

pins passing through holes in said studs in the ordinary manner, and through this dial 20 passes froni the ordinary watch-movement the shafts that Carry the ordinary minute and hour hands, the minute-hand being preferably extended, so as'to project over the dial 1-1 and to the dial S, and the hour-hand to said dinl.

Over the hands and-dials is placed the'ordinary crystal, fitting in the ordinary riut used for holding it.

'without regard to whether the watch is either fast or slow New York time. The watch wild thns indicat the correct-time in London. 'It 'is only necessary to move the dials 8 and 11 so that th'e' proper ho'ur'or fraction of aii honr and' minutegor fractio of a minute division areopposite 'the hour and minute hands at 'any place `where there isa difl'erence of time between such place and the place where the watch 'is rdinarilyuseththe hands indicating on the ordinary dia!" the time 'in the latter' place to'` enable the time to be ascertained'withont caleulation at such different place after this sin:

ple adj'ustment has 'been made.

'Ido not confiie my invention to the specific struciurejnst described with' reference to the drawings, as iiimay be varied within widelimits. Thusthe two snpplemental independently-adjustabl'e dials may be placed in a rim 'provided with' arms extending over the crystal of the watch' and held by the bezel that holdssaidcrystal, so that 'the faces of said ad- 4 5 and seetional view at Fig. 6; or they may be j istable dials and the ordinary hands and the ordinary fixed dial can be seen and inspeeted simult'aneously, as'shown in plan view at Fig.

arranged under the crystal but. above the hands, a sufficient space being left to permit said hands to move frcely; or they may be arranged to work in grooves castin the erystal of the watch andspringnto th'em,and so that their t'ace'sand the hands, and the ordinary fixed dial can' be seen and inspected simultaneously, as clearlyshown at Fig.7 ofthe drawings. In all of these cases the two s'upplemental independently-adjustable dials may be adjusted by the fingers", and they may, be of 'any desired ma- .teriaL-as metal, paper, pasteboard,-&c.-or

they "may be made of paper or pasteboard, 06 such size as .to be within the ordinary hourcircle ot' the fixed. dial 'witl which they are to be'sed, and after having been properly ad- -ju'sted with. reference to the ordinary hands,

temporarily pasted or glued or otherwise sccured toeither the inside or outside of the crystal, so that the hands and their faces and the ordinary fixed dialcai be seen and inspected simultaneously, and be'removed and others adjusted when moving from place to place. Snch paperdials are shownin plan and sectional views at Fig'. 8 of the drawings'. 'In`all' of these cases the enter supplenental dial can able clocks, 'or other movable time-pieces and fiXed-tine-pieces, as well as to watches, and any skilled mechanic could attachthem inthe maner above described' or .in various. other ways, and such time-piece would` still contain my invention-so long asthe ordinarydial 'and handswer used 'in connection with two supplemental dialscapable of ndeiendent al- I j nstment with reference to. the ordinary hands, I

so that'their faces 'and the hands can be seen' 'simultanonslyn for. the purpose described. 8

These supplenental dials ca'be ap'plied to old* time pieces as well' as new, so as to efl'ect the object above described:

f By the use of myinvention the time-can be ascertained at any two localitics at on'ce w'ithout movingthe hands of the 'time-piece inde- 'pendcntly of the rnotien imparted to them by the time-movemen t, and thus withoutvliability of the time-pieceiosing its rating, and a traveler can, after adjustig the two snpplemental .dials upon. his time-piece, aseertai the local time at auyglace he has reached. A shipmaster can also do the same when he is at an chor at any port. 'and this without the incon ve ience of and injury incident to resetting-it Ioo to indicate the time at 'the locality where it is ordinarily used. Having th uslescribed my invention and the meiits it possesses, what I claim as new, and desire to secure by Letters Patent, is- `o' 1. In comliination with the ordinary fixed dial and hands of a time-piece. twosupplemental independently adj stablc dials, one 'having on its face the divisions of minutes and the other of hours, substantially as and for the o purpose described. 3 2. In combination with the ordinary fixed dial and'hands of a' time-piece, two supplemental independently -adjustahle dials, one hearing on-its face thedivisions ot'mintes and 5 the other of hours, with means for adjusting the same with reference to said hands, withom noving the latter, substantially as described.

3. ln comlinatian with the plate 4, the supplcmental independontly adjustable dials 8- and 11, substantially as described. 4. In combination with the plate 4, the supplemental independently-adjustable dials 8 and 11, provided with annular racks and shafts provided' with pinions and`wheels, substan- ,325

tially as described. 4
